Infer MapReduce types where possible ------------------------------------ Key: MAPREDUCE-1411 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1411 Project: Hadoop Map/Reduce Issue Type: Improvement Components: client Reporter: Tom White Assignee: Tom White
Currently users must specify the output types of the map and reduce if they are different to the default (LongWritable keys, Text values). In many cases this information is available to the system from the user-supplied mapper and reducer, so it would be nice if the user didn't have to specify them in two places. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
